Although no British ship has joined the ill-fated flotilla from Athens to Gaza, this week activists in the UK have been lobbying Prime Minister David Cameron and the Greek ambassador to "guarantee their safe passage".
As commuters sipped their morning lattes on London's Southbank, a small band of activists boarded their own Free Gaza "flotilla". But it was a far cry from the Mavi Marmara. The vessel was hired from London Party Boats and the downstairs bar was declared open as passengers stepped aboard. They included Green Party MP Caroline Lucas and Faithless guitarist Dave Randall.
The boats of the second Gaza flotilla are expected finally to set sail this weekend from the Greek coast.
The flotilla was initially planned to sail on Tuesday but a number of delays, including a mysteriously broken propeller shaft and anonymous complaints to the Greek Coast Guard, have delayed embarkation.
Irish Palestine campaigners have accused "agents of Israel" of damaging a ship they planned to send to Gaza.
According to the Ireland Palestine Solidarity Campaign, the ship, the MV Saoirse, had been "sabotaged". It accuses "agents of Israel" of the "extensive" damage but does not provide any evidence to back up the claim or detail the alleged damage.

Middle East minister Alistair Burt became the first Foreign Office minister to visit the Gaza Strip in five years on Tuesday, as he toured a United Nations school in Jabalia refugee camp and met business leaders in Gaza City.
